Detailed Description
The present application is further described with reference to the following drawings and detailed description (including examples), but not intended as a basis for limiting the technical solutions of the present application. In the following examples, the details which are not described in detail are all common knowledge in the art.
The method adopts the novel crochet machine with the three-dimensional crochet refitting assembly to produce the three-dimensional crochet fabric. The produced three-dimensional crocheted fabric can be compounded with a base pad to form a foot pad product.
Example (b):
referring to fig. 1-13, in the present embodiment, the novel crochet machine equipped with the three-dimensional crochet modification assembly comprises a crochet machine body; the crochet machine body comprises a needle bed 1 and a warp guide bar 2 which are horizontally configured, and a first weft guide bar 3 and a second weft guide bar 4 are configured above the needle bed 1 in tandem; the three-dimensional crocheting modification assembly is also included; the three-dimensional crocheting modification assembly comprises a three-dimensional forming toothed plate 5 arranged between a first weft guide bar 3 and a second weft guide bar 4 (the three-dimensional forming toothed plate 5 is fixed on the crocheting machine body through a connecting piece); the lower edge of the three-dimensional forming toothed plate 5 is provided with a group of needle passing notches 501 corresponding to the needle grooves on the needle bed 1, so that the crochet needles 9 installed on the needle grooves can pass through the needle grooves when reciprocating back and forth, and a second weft three-dimensional forming tooth 502 is formed between two adjacent needle passing notches 501.
In this embodiment, rounded corners are processed at the front and rear sides of the end of the second weft three-dimensional forming tooth 502.
In this embodiment, the back side of the second weft three-dimensional forming tooth 502 is provided with an inclined guiding surface 5021 engaged with the end fillet.
In this embodiment, the inclined guiding surface 5021 is a plane, and the inclined angle θ formed between the inclined guiding surface and the horizontal line is 60 °.
In this embodiment, the upper end of the inclined guide surface 5021 is vertically higher than the needle groove on the needle bed 1.
When producing the crochet fabric, like the crochet machine in the prior art, a crochet needle 9 is required to be arranged in a needle groove of a needle bed 1, a looper 10 is required to be arranged in a needle groove of a warp guide bar 2, a needle tube 11 is required to be arranged in needle grooves of a first weft guide bar 3 and a second weft guide bar 4, a warp 6 is arranged on the needle head of the looper 10, and a first weft 7 and a second weft 8 are respectively arranged on the tube body of the needle tube 11.
